Cooler Master eXtreme Power Plus 500W good for GTX 660?

Solution
Hi, seems your 5770 is using about 200 watt at load (http://www.tomshardware.com/reviews/radeon-hd-5770,2446-15.html) Gtx660 should go to about 150 so it should be fine, as it loads PSU less. You would experience shutdowns if there is not enough power. and more PSU power means you are not running it at max, they should then sound quieter and live longer, emitt less heat, as it is not loaded to 80-100% all the time.
